It looks like that version identifier v2.0.1 is from the /themes/default/css which is not currently used in 7.7. We build our css from /styleguide/less including some files in /styleguide/less/twitter-bootstrap originally based on version v2.2.2. On top of that we have a significant amount of custom LESS files (mostly in /styleguide/less/sugar-specific). Because Bootstrap 3.x introduced a number of changes to how an application DOM is structured, and we have so much customized CSS, we currently have no plans to upgrade our bootstrap.less files. However, we do continue to upgrade our Bootstrap plugin Js files individually as needed to the latest versions along with any CSS changes that are needed to support those upgrades.
